Drey Wright and Fraser Murray contest a long ball down the left, and Murray gets the better of the St Johnstone defender, who is forced to foul him. Easy yellow card.

The visitors clear the free-kick though, and come forward through through Makenzie Kirk, who zips a shot towards goal. Kieran O'Hara was always behind it.

Motherwell's Lennon Miller does well under pressure to bring the ball down inside the area but blasts it well wide from a tight angle.

Where's my Arthur Montford tweed jacket? I've just witnessed the most almighty 'stramash', as he likes to call it, in the Aberdeen penalty area. Aberdeen threw bodies in the way, blocked shot after shot and only saw relief when Jordan McGhee blasted wide when he might have scored.

A real throwback. Dogged defending by the Dons, who're fiercely protective of their slender advantage.

Much better from the home team as Mo Sylla brushes Pape Gueye aside and thunders downfield.

There follows a frankly bonkers series of flicks, headers and balls across the face of goal, none of which find the Aberdeen net. Simon Murray has a couple of cracks but can't direct his efforts on target.

The Dons clear, but Dundee recover and send it back into the box through Lyall Cameron. After a few ricochets, it drops for Jordan McGhee on the volley eight yards out. He stabs wide.

Big chances spurned.

Jota has been electric down the left - and United have no answers for him.

In his most recent expedition, he skips past Luca Stephenson before picking out Adam Idah in the box, though the striker's effort is blocked behind.

Is Aberdeen striker Kevin Nisbet finding form, as new signing Oday Dabbagh watches from the bench?

It's two goals in two games now for the on-loan Millwall forward.

You could just see Jota warming to his task down the left-hand side. His influence was just growing and growing and that is an excellent finish. Effortless almost.

He just seemed in total control of what he was doing and what the outcome would be.

Jim Goodwin has a lot of thinking to do. Dundee United did well for a spell but are in danger of this getting away from them before half-time.

Kevin Nisbet was in the right place at the right time to score Aberdeen's opener at Dens Park.

There's a swagger about Aberdeen now.

Jeppe Okkels canters down the left flank, skips inside and bends a low effort towards the far post which is brilliantly tipped away by Jon McCracken.

St Johnstone have got themselves up the pitch, but it's Kilmarnock who hit on the counter through Fraser Murray.

He skips by a few challenges on the halfway line and paces down the touchline, before crossing low for Bobby Wales - but it's just too far in front of the striker.

Jay Henderson has given Ayr the lead against Falkirk with a penalty. How important might that goal be in the Scottish Championship title race?

After doing precious little for very nearly half an hour, Aberdeen spark into life. Ante Palaversa very nearly gave them the lead but from the resultant corner, the ball is recycled well and Kevin Nisbet times his run well to smash the ball into the roof of the net.

Aberdeen lead at Dens, again. They've only lost two of the previous 30 league encounters. Dundee's bogey team?

A rarity for Callum McGregor that goal, scoring from inside the penalty area. All his others this season have come from further out.

Yet again, he makes a big contribution to set Celtic on their way.

And so close to a second with some great footwork moments ago.

His influence is undoubted.

Another excellent piece of attacking play from Celtic captain Callum McGregor as he nearly snatches his second of the day.

Once again, he jinks his way around a number of United defenders before letting fly. This time he is on his right-foot, however, and his curling effort just whizzes past the post.

A first chance of the afternoon for Dundee United and it was a dangerous one.

Midfielder Allan Campbell surges forward into the host's penalty area but can't get his foot onto a low cross on the left. Big opportunity spurned.
